Aluminium foundries that cast aerospace, automotive, and other commercial parts see process benefits when using RGW filters. Benefits include more consistent pouring times, easier recycling of gating, reduced abrasion on moulds and mould coatings, and improved fit with the filter pocket to prevent metal bypass. Rigid Glasweve filters are less dense than aluminium, so they float to the top of the melt and are removed during regular fluxing and dross removal. After a casting has solidified, RGW filters are remelted with the gating. Compared to CFFs, Rigid Glasweve filters provide foundries with a more cost-effective solution with no distinguishable difference in casting quality.

Pyrotek Offerings

Pyrotek Rigid Glasweve filters are manufactured with tight dimensional tolerances—within 0.5 millimetres—and are available in a variety of shapes, sizes, and materials to fit filter pocket dimensions and match flow rates of 10, 15, 20, and 30 pore-per-inch (ppi) CFF filters. Since the material, shape, and weave style filter can affect the flow rate, Rigid Glasweve filters can be designed to replicate the existing filter and flow rate so as to not affect the casting process.
